Notion vs iA Writer
While Notion can be used as a minimal writing environment similar to iA Writer, it's much more powerful than that. Teams of all sizes use it to collaborate on documents, build knowledge bases, and even schedule automations. Unlike Ulysses, Notion is available on all platforms.
iA Writer is geared towards professional writers who want a clean and simple tool to create and organize their work. It aims to remove all distractions, so the writer could focus on their work.
